Ollie’s Frozen Custard was started by Bill Jamison in 1985. Bill has been eating custard since the age of 4 years old. His favorite custard stand was "The Sycamore Drive-in" in Indiana. Back then a cone of custard was 5 cent and a sundae was a quarter.

He opened Ollie’s serving 3 flavors of custard- Vanilla, Chocolate and the flavor of the day. Through much trial and error-mostly error- he slowly added more flavors to his menu and baked his own waffle cones.

Ollie’s was the second custard stand to open in northern IL. Word quickly spread throughout the town, of the tasty treats-Bill was creating at his stand. The business soon became the place to meet and eat premium frozen custard. After 5 years in this location- it became clear that Bill needed a larger building and parking lot, to meet the ever-growing demand for his brand of custard.

Ollie’s is so popular, that it isn’t uncommon for people in a 50 mile radius of the stand, to get in their car and drive many miles to enjoy some of Bill’s custard. The menu has grown over the years to include many new popular flavors-served in cake and waffle cones. In addition to the cones- a large variety of sundaes, shakes and blasts make it very difficult to decide which to try first. Even though the line at the order window extends around the building a lot of the time- the staff can quickly take your order and have it ready, before you can put your change back your in your pocket.
